Several months ago I posted about being diagnosed with OSA, obstructive sleep apnea. That was 12/31/08. Before sleep therapy with a CPAP machine my rides suffered because my body was not regenerating at night with the proper deep REM sleep. The constant awakings gasping for breath and getting up to use the bathroom multiple times during the night made for a miserable day. Once treatment began on 1/2/09 my oxygen saturation levels have returned back to normal. During the OSA my o2 Sat. levels dropped to 72%. Not good for your brain and body organs. Now it is back in the upper 90% range and I get a full deep sleep lasting 6-8 hours and I awake fresh and my sore muscles are relaxed. What I did not expect was weight GAIN. Since I was lying still all night rather than tossing and turning and getting up all night (buring calories at night) I gained 11 pounds from January to April. Not my objective. Once I recognized what was happening I began to back off the extra food and watched what I ate and ate less of what I did eat I have lost the 11 pounds and then 5 more since April. I cannot say enough how this therapy has helped my overall health. I may have to continue using it, but a small price to pay to avoid a possible stroke, hearth attack, or any other health related issues that sleep apnea may attribute. I say all of that to say if you snore alot and wake up feeling more tired than when you went to bed there is a good chance you have OSA. It may not be as severe as mine was, but a sleep study is worth the cost to find out. I still weigh 253, but dropping. I got as high as 266 back on April. My age is 56 so I fall in that category of potential OSA patients.
